<h1 class="topictitle1">手动执行备份</h1>
<div><p>当您需要立即执行一次备份任务时，可以通过手动备份实现。</p>
<div class="section"><h4 class="sectiontitle">背景信息</h4><ul><li>手动备份时，SLA中定义的参数（<span class="uicontrol">“<span>失败后自动重试</span>”</span>除外），如<span class="uicontrol">“<span>限速策略</span>”</span>、<span class="uicontrol">“<span>自动索引</span>”</span>、<span class="uicontrol">“<span>应用一致性备份</span>”</span>会应用到手动备份任务中。</li><li>手动备份产生的副本保留时长按照SLA中定义的保留时长进行保留。<p>如果手动备份时选择的保护策略未在SLA中定义，则产生的备份副本保留时长为永久保留。如SLA中未定义永久增量（合成全量）备份，而手动备份时选择的是永久增量（合成全量）备份，则本次手动永久增量（合成全量）备份产生的副本保留时长为永久保留。</p>
</li><li>如果SLA定义了复制策略或归档策略，则执行手动备份时，系统会按照SLA的定义执行一次复制或归档。</li></ul>
